2018-10-23RISC-V: Avoid corrupting the upper 32-bit of phys_addr_t in ioremapVincent Chen1-1/+1
For 32bit, the upper 32-bit of phys_addr_t will be flushed to zero after AND with PAGE_MASK because the data type of PAGE_MASK is unsigned long. To fix this problem, the page alignment is done by subtracting the page offset instead of AND with PAGE_MASK.

2017-11-30RISC-V: io.h: type fixes for warningsOlof Johansson1-1/+1
include <linux/types.h> for __iomem definition. Also, add volatile to iounmap() like other architectures have it to avoid "discarding volatile" warnings from some drivers. Finally, explicitly promote the base address for INB/OUTB functions to avoid some old legacy drivers complaining about int-to-ptr promotions. The drivers are unlikely to work but they're included in allmodconfig so the warnings are noisy. Fixes, among other warnings, these with allmodconfig: ../arch/riscv/include/asm/io.h:24:21: error: expected '=', ',', ';', 'asm' or '__attribute__' before '*' token extern void __iomem *ioremap(phys_addr_t offset, unsigned long size); sound/pci/echoaudio/echoaudio.c: In function 'snd_echo_free': sound/pci/echoaudio/echoaudio.c:1879:10: warning: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type [-Wdiscarded-qualifiers] Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
2017-09-27RISC-V: Device, timer, IRQs, and the SBIPalmer Dabbelt1-0/+92
This patch contains code that interfaces with devices that are mandated by the RISC-V supervisor specification and that don't have explicit drivers anywhere else in the tree. This includes the staticly defined interrupts, the CSR-mapped timer, and virtualized SBI devices. Signed-off-by: Palmer Dabbelt <palmer@dabbelt.com>
